In Birt-Hogg-Dubé (BHD) syndrome, germline mutations in the Folliculin (FLCN) gene lead to an increased risk of renal cancer. To address if FLCN is involved regulating cellular signaling pathways via protein and receptor phosphorylation we determined comprehensive phosphoproteomic profiles of FLCN-POS and FLCN-NEG human tumor cells (UOK257). UOK257 misses the folliculin (FLCN) gene, whereas UOK 257-2 harbours a lentiviral rescue of the FLCN gene. Experiment performed in duplicate. This data set is linked to PXD021346 that describes phosphoproteomics results for human renal tubular epithelial cells (RPTEC/TERT1).
